Product Description

Center Brand ISR fittings are precision-made fittings that contain a ring of high quality lead free solder in each capillary socket. When heat is applied, the solder is released into the gap between the tube fittings, resulting in a totally sound joint without the need to end feed additional solder. Light and neat they make handling and installation easy. The fittings’ compact dimensions make them an ideal choice for use in areas where there is limited space. Their smooth lines minimise flow restrictions and are unobtrusive on exposed pipelines. Center Brand ISR fittings are manufactured from copper, gunmetal or other dezincification resistant alloy (DZR). The Center Brand ISR joint is created through the principal of capillary action. When the fitting and tube are assembled and heated to correct temperature, solder applied to the mouth of the fitting becomes molten. Capillary attraction ensures the solder is drawn into the gap between the tube and fitting, forming a sturdy and reliable joint.
